How do I recover my product key from MSDNAA/DreamSpark purchases prior to Summer 2013 semester?

Owens current DreamSpark store was created during the Summer 2013 semester. The previous DreamSpark store license has expired and is no longer available to Owens. If you have lost a keycode from the previous store (purchases prior to the Summer 2013 semester) search your emails for the receipt. You can also reach DreamSpark student support from their support page for assistance with key code retrieval from the former store.
